No change.
Well, I nearly had the right answer here. I tried a simple test project, using black text, and saw the effect you describe. Zooming into the display (Control+scroll) revealed the difference pretty clearly, since I could see the colors of the anti-aliased pixels. In the NSTextField text, LCD font smoothing is being used; in the drawn text, it is not. There is behind the scenes magic when drawing text, that determines whether it knows that LCD smoothing can be applied. When I turned the LCD smoothing option off in System Preferences -> General, the text rendered the same in both cases. Note that your choice of text color made the problem appear worse, because sub pixels were apparently being turned on both for smoothing and for coloring, which made the text look bolder than if it had been black. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
